To all whom z't may concern:

Be it known that I, WILLIAM ODONNELL,

a citizen of the United States, residing at y Oklahoma in the county of Oklahoma and State -of Oklahoma, have invented' certain new and useful Improvements in Piling, of which the following is a specification, reference being had to the accompanying drawin s.

tlriihe invention pertains to improvements in piling.

An object is to provide improved means for sinking the pihng.

Other objects and advantages of the invention will be set forth in the ensuing description. n

One embodiment of the invention in practical form is shown by the accompanying drawings.

Figure 1 shows a river-bed and shows four of the improved piling which have been driven to grade and are supporting trestlework which carries a traveling crane for handling and sinking additional piling.

Fig. 2 is a similar elevation view showing how the sections of piling are handled and how certain water supply connections are made. v Y

Fig. 3 is an enlarged 'plan view of a clamp.

Fig. 4 is a'similar view of a clamp and a pivoted arm.

Fig. 5 is a sectional view on st ill larger scale, of the lower end of the improved piling. A

Fig. 6 is a plan view on still larger scale, of a boring foot at the lower end of the piling.

Fig.'7 is an elevation view of the borlng foot and a .fragment of a shaft which drives it.

Like characters of reference designate like parts in all the gures of the drawings.

In this invention the piling includes an outer tube or casing 10 of anyr suitable material, such, for example, as common large gas pipe or boiler-iron, according to the size of piling required; and this casing may be of any suitable shape in cross-section,

such, for example, as round, hexagon, 'or' Octagon.

This casing 10 may also be of a thickness adapted to support its load by its own resistance to bending or crushing strain, or, after being sunk to place, it may be lled with any suitable material, such, for example, as concrete.

In providing for sinking the casing 10, a boring foot 11 is arranged to revolve in its lower end and bore or drill its way downward into the sand or rock.

This boring foot 11 is provided with an axial neck 12 terminating in a head 13, and the neck and head are revolubly embraced by. a separable bearing block -14 which tightly lls the lower end of the casing 10.

This` bearing block'l/i, which must be in two parts for assemblage with the head and neck of the boring foot 11, is held together by the embracing lower end of the casing 10, but for greater convenience in assembling the parts an iron band 15 may first be ut on the lower end of the block hot and' e slorunk tight, the casing resting on said To drive the boring foot 11, a shaft 16 is extended down through the axial center of the casing 10 and has its squared lower end inserted in the head 13 of said foot.

In arranging to drive this shaft 16, its upper end is provided with a gear-wheel 1.7 above the upper end of the casing 10, and this gear-wheel is driven by a worm pinion 18 on the shaft 19 of a suitable motor 20.

' The motor 20 may rest on a platform 21' which is attached rigidly to the casing 10, and said platform is supported by corner braces 22 which arev in turn supported by two bands 23 which clamp removably around the casing 10.

In making ready to sink the piling, the boring foot 11 and driving shaft 16 are put in place in the casing 10; the supporting platform 21 also being attached to the upper end of saidcasing with the motor-20. in place thereon and operatively connected to said shaft 16; all this being done while the casing 10 lies horizontal and in position for convenient assemblage.

By use of the boom 24 and tackle 25 of of the platform 21 by four rods or cables 28.

With the casing 10 in vertical position,

Vthe motor 2O is started and the boring foot 11 begins to bore downward under the weight of the casing and .attached parts.

To remove the material resulting from the boring operation, the boring foot 11 and its` neck and head are bored out axially, as at 29, and the driving shaft 16 is made tubular.

A pipe 30 leading from a pumping engine 31 or other source of water supply, has one of its branches, 32, connected to the upper end of the tubular shaft 16, this connection comprising a portion of fiexible hose 33 which attaches to said shaft by a swiveled goose-neck 34; and by forcing water down said shaft 16 the dirt, sand, and other material cut loose by the boring foot 11 is washed up on the outside of the casing 10 as shown in Fig. 1.v

A stuling-box 35 to prevent undue leakage of water upward past the lower end of the driving shaft 16 ma be provided and secured to the upper sur ace of the bearing block 14.

A little concrete 36 may be poured around the stuling-box 35, if desired, and will tend to hold said stuling-box still.

To revent the Casin 10 from being revolve by the action o the boring foot 11, a clamp 37, shown in Fig. 4, may embrace said casing, a long arm 38 being pivoted to this clamp on a horizontal axis to allow the sinking movement of the casing 10, and havin its outer or free end attached to any suitable fixed object.

After once starting to bore a piling downward into the ground or into sand or rock the forced flow of water down through the boring foot 11 should not stop, even though the revolution of the foot and the boring be stopped for a time.

But since in adding another section of casing 10 to that already sunk it is necessary to uncouple the goose-neck connection 34 at the top of the shaft 16 and remove the gear-wheel 17, platform 21, and other parts, an additional means of maintaining a forced flow of water down through the borin foot must be provided.

providing this means, a pipe 39 is led down the interior ofthe casing 10 alongside the shaft 16 and into a port 40 in the bearing block 14, and this port 40 is arranged to be in communication with at least two of a series of ports 41 which lead down through the head 13 of the boring fo'ot and into communication with the central bore 29 thereof.

The second branch, 42, of the pipe 30 is connected to the upper end of the pipe 39 by a flexible hose 43, so that while tubular shaft 16 is outof service water is supplied to the boring foot 11 through said pipe 39.

A check-valve 44, adapted to prevent back flow of water up the shaft 16, is arranged in the head 13 of the boring foot 1.1 and adapted to seat against said shaft; and likewise a check-valve 45, to prevent back flow of water up the pipe 39, is arranged in the port 40 and adapted to seat against the lower end of said pi In removing the platform 21 from the top of the sunken section of casing 10, the o enings 46 in its supporting clamps 23, est shown in Fig. '3, pass over the horizontal portion 47 at the upper end of the pipe 39; and after said platform has been mounted on the new section and said new section suspended over the sunken section as shown in Fig. 2, water supply may be restablished through the shaft 16 and the hose 43 and pipe connection 47 uncoupled from the u per end of the pipe 39 before bringing tlli) two sections together. v

There will be no trouble in coupling a new section of the shaft 16 and a new section of the pipe 39 to the sections sunk with the casing 10.

After the casing 10, comprising one or a number of sections, has been sunk to grade or to the desired depth, the platform 21 and attached 'parts may be removed, as may also the shaft 16 and the pipe 39; and the casing 10 may then be filled entirely to the bottom with concrete or any substance adapted to strengthen and reinforce said casing.

The boring foot 11, together with its bearing block 14, remains as a permanent footing for the casing 10.

It will be seen that there is provided: a

piling having a revolvable point which will bore its, way downward without the necessity of revolving the entire piling; that there is provided means for maintaining a con-v tinued and forced supply of water through the piling and'through its revolvable point to wash a clearance for the piling; and that the objects of the invention are fully attained.

Having thus described the invention, I claim 1. In piling, a tubular body having at its lower end a boring member, a tubular shaft leadingl down the interior of the body and operatively engaging said boring member, means for forcing water down said shaft to remove the material resulting from the action of the boring member, and means for supplying water to the boring member during the time the shaft is out of service.

2. In piling, a tubular body embracing at its lower end a bearing, a boring foot arranged below said bearing and having an axial neck extending up into said bearing, said foot and neck having an axial port opening downward onto the boring face of said foot, a tubular shaft extending down the interior of the tubular body and operatively engaging said port to drive the foot, the bearing having a port, the neck of the foot having ports leading from its central port into communication with the port of the bearing, and a pipe leading down the interior of the tubular body to the port of the bearin 3.
